Online event without a venue
See what is left out when an event has no venue — in the admin: Content › Events
Date:
An evening online event: it has a date and a time but no venue, so its page shows no venue card.
The "Venue" field is optional. Leave it empty and the event page shows only the time and the description.
For an online event, give the way to join in the description, for example as a link to the invitation.
